HEAVY METAL ACCUMULATION AND OXIDATIVE-ANTIOXIDATIVE STATUS IN ANGORA GOATS DEPENDING ON AGE

摘要

This study intends to designate the alterations in the oxidant-antioxidant parameters and the heavy metal concentrations based on age of Angora goats bred in Cankiriprovince of Turkey. In order to conduct an analysis of serum heavy metals including aluminum (Al), chromium (Cr), iron (Fe), copper (Cu), cobalt (Co), tin (Sn), cadmium (Cd), selenium (Se), vanadium (V), manganese (Mn), zinc (Zn), lead (Pb), arsenic (As), nickel (Ni), a total of 120 blood samples were taken. Concentrations of plasma vitamin E, vitamin A and β-carotene, concentration of malondialdehyde (MDA), activities of catalase (CAT) and superoxide dismutase (SOD) were evaluated in the erythrocytes. Correspondingly, compared to young goats, the adult goats had substantially higher levels of Al, V, Mn, Ni, As and Sn. With respect to the young goats, the vitamin E concentration and SOD activity measured in adult goats were lower and the MDA concentration was considerably higher. Consequently, it was seen that aging affected the oxidant-antioxidant parameters and heavy metal concentrations in Angora goats.
